when i read the word SANGAM ... i remember my first year thamizh class ... we had a hot discussion, with somebody quoting that SANGAM itself is not a Thamizh word ! The reason he gave was like in the word SANGAM -> the first letter "sa" as per thamizh dictionary does not exist ! the sa existing is actually cha -> as we are using it dually ! Is this true about SANGAM ?
